Still a'furtheiobject is to provide a support for the bumper which is adapted to be secured at two spaced points to the body frame of the automobile and at a third point to the chassis frame ofthe automobile.

l/Vith these and other objects in view, our invention consists in the construction, ar-

rangement and combination ofthe various parts of our *bumper construction, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in our claims and illustrated in the accompanying drawings, in which: l

s igure 1 is a perspective view of our 1mproved bumper. j n

Figure 2 is a top plan view of thel same with parts of the yautomobile body indicated therewith.

Figure' 4 is a sectional view taken on the line 4 4 of Figure 2 illustrating the split ring member for connecting the ybumper elements together. v v

Figure 5 is a detail sectional view taken on the line 5 5 of Figure 2; and

Figure 6 isa sectional view taken on the line 6 6 of Figure 3 illustrating the cross member of the chassis and the connection with the bumper support thereto.

In the accompanyingV drawings, we have used the reference character Ll() to indicate generallythe side body .frame and 12 the rear cross body frame. The fra-meinembers .10 and 12 are connectedl together by-anend piece 14 which is curved and which is also channel shaped in cross section.

' The entire body frame of thel automobilev rests upon the chassisformed of'a side frame lmember 16 and a rear cross'framefmember 18. The frame members 16 and18 form the car frame or `chassis and are connected tois a sectional view taken on the Y fof the bolts 30.j

gether'.` ,The chassis cross frame 18is substantially channel shaped-in cross section as clearly illustrated in Figure Spf the drawings. i i

yOn the side of the car body-and connected thereto, is a rear mud guard or fender 20 which is adapted to be protected by our bumper which we will. rhereinafter more fully describe. l f Y The position of a spare tireh22is clearly illustrated in F igure 2 of` the drawings. Our improved bumpery is preferably formed of a pair yof 'tubular bumper elements 24 which are connected togetherby a pair of split Yringelements 26. The split .ring Aelements 26 are each formed with tubular portions for Areceiving the tubular bumper elements 24. Y A f .f Between thetwo tubular portions ofthe split rings 26, we'provide a space 28 where#` in a bolt 30 may, beextended through 'portions of the split' ring 26 for connecting the bumper elements to'prope'r` supports and at the same time to'fastenor tighten the split v rings around eachl of thetubular bumper ele-` ments `24. A short connecting piece 32 spaces V-the two tubular portions lfrom each other and defines a portion through which the bolt-s may be extendedg vThe, split Vring 26 is formed with `overlapping endsv as at 34 through which the bolt 30 also extends.l It will bej'noted thatV when' the bolt 30 has been tightened, that the overlapping ends are Vdrawn towards thepconne'cting portion 32 wherein thesplit-ringwill be tightly held upon the tubular elements 24.` The cappedfwith small caps 36 for appearance salie. Y

port A includes two strap like'elements''38 lends of the tubular bumper elements are I and 40. Both of the kelements 38 and 40 i are connected to the split rings 26 by'means n tially parallel'. portionsl 42f-through 1 which may be extended a bolt or`the"like 44 whereby the two elementsy are connected together. y.The bolt 44 serves in connection with the 38 and .-40 project l.

bolt of each of the bumper elements to properly position the supportfA 'relative t the bumper elements 24.

The rear or inner end of the portioniQ of' the elemen't188 4isturned'a quarter turn as at for providing a flat horizontal end 48 which is provided with an opening 50. The end 48 projects up a short distance above the normal'level of the element 88-V as clearly Y then terminates in a` straight portion extend- 'l in,

forwardly as atb, f I e he rear end `fthe portion 56 is provided with a'quarter bend or turn 58 so that a Hat liorizontalend v60V is also formed uponthe inner end of the member or element 40. The end 60 is provided with a pair 'of openings '62' through which boltsfefi'niay be extended.

Tlieend 60 rests upon the chassis `cross frame member 1.8 and the openings thereof register witliopeni'ngs formed in the cross frame 1.8 ,so that the bolts 6ft may be used for securely anchoring the inner end of the memberlO to theautomobile chassis. The portion'G of the 'member' 40li'as connected' to it a'iiangle bracket 66. 'The angle bracket may beriveted or bolted to 'the portion 56 and yprovides a ishortoflset vextension `whichy is adapted to litup against the' underside of the rear cross body frame 12. The Langle bracket 66 isf provided -with a small opening 68 through which ya boltorthe like 70 may be extended for 4connecting the angle 4.bl'aclget to the rear body Vcio',ss`fra1ne 12.

j It will be noted therefore, ythat the sup- `port is` connected attwo1 spacedpoints to Vthezbody. frame and Vat a thirdlpointto `the f chassis proper.' lThe connectionsarespaced lapart so that Ya three point connection between thebumper support A' and the automobile is had wherein the/parts may be Asecurely anchored to the automobile and` will withstand the necessaryhard usage to which a bumper is subjected.

'.Some changes maybe made in the con-v struction and arrangement of the parts of `our device without departing from the real spirit and purpose of our invention, and it is our intention to cover by our claims, any modified forms ofv structure or use of mechanical equivalents, which may be rea- Y necting said bumper elements in spaced relationship: and means for supporting said bumper elements on the frame of an automobile, said means including a pair of members eachY having partsy connected t'osaid fastening means and projecting towards each other and having parts arranged parallel to each other and connected together, one of said members being of greater length than the other and havingy connection with the automobile frame at a point spacedfrom and independent of the Vother of said' members.
